Hereinafter, an elevator occupant monitoring method performed by the controller will be described with reference to the accompanying drawings.

4 is an operation flowchart of an elevator occupant monitoring system according to an embodiment of the present invention. The elevator may be up and down, but the following description will be made assuming when the elevator is raised in the present embodiment.

When the occupant gets on the elevator and presses the number button of the desired floor among the number buttons mounted inside the elevator, the control unit 13 detects the pressed number button and stops at the floor corresponding to the number, and opens the lift case door. When it is lowered, the closing door is closed and the control of repeatedly moving up is performed. At this time, the controller 13 checks whether the elevator reaches the final target floor whenever the elevator stops (S401).

After that, when the elevator reaches the final destination floor, the control unit 13 checks whether the occupant falls out of the elevator through the sensor (S402). This is a process of first detecting that an emergency situation has occurred to the occupant if the occupant does not get off even when the elevator reaches the final destination.

After that, the control unit 13 drives the camera (S403) to take a picture of the inside of the elevator when a passenger's getting off detection signal is not input. This is a process for the controller 13 to secondarily detect whether the lift occupant is actually in an emergency situation.

Thereafter, the controller 13 checks whether the occupant is moving from the image acquired from the camera (S404), checks whether the occupant is moving (S405), and if it is determined that the occupant is not moving, the controller displays an elevator internal image input from the camera. Compression is transmitted to the monitoring center 300 through the communication unit 18 connected to the Internet network and automatically calls the first monitoring center telephone number stored in the memory 14 (S406). In step 406, the through-circuit path unit 15 that receives the monitoring center call control signal by the control unit 13 generates a DTMF signal corresponding to the telephone number and outputs it to the telephone station. The digital signal processing technology and image compression technology related to such motion determination are well known prior to the filing date of the present invention, and detailed description thereof will be omitted.

Thereafter, the control unit 13 detects a tone signal relating to the called party's telephone state information from the telephone station (S407). After that, if the tone signal detection result is a ringback tone signal (S408), the controller 13 counts the ringback tone signal to determine whether a count time exceeds a reference time, and then checks whether there is a response within the reference time (S410). If there is a pre-recorded emergency situation radio message is output (S411), if there is no response call the second stored monitoring center number (S412). On the other hand, if the tone signal detection result is a busy signal (S409), then another similarly stored call center monitoring number is called (S412).

Hereinafter, the control unit 13 performs step 412 for calling the other monitoring center phone number and repeats until any monitoring center answers the phone.

The control unit 13 outputs the recorded emergency situation radio message when an arbitrary monitoring center answers the phone (S411) and ends when the voice call between the monitoring center and the elevator occupant is completed (S411).

As described above, the elevator occupant monitoring system according to the present invention detects whether an emergency has occurred to the occupant by using a sensor and a camera mounted in the elevator, and automatically connects to the monitoring center in case of an emergency, and informs of an emergency radio message. As it has a useful effect to protect the elevator occupants.

Furthermore, the present invention transmits the image of the inside of the elevator to the monitoring center through the Internet in case of emergency or emergency to the occupant of the elevator, so that the monitoring center manager can monitor the current situation of the elevator occupant and take necessary appropriate measures. Has an effect.

Furthermore, the present invention detects the case where the call of the monitoring center is busy or unable to answer the call due to the absence of the administrator, and automatically calls another monitoring center to protect the elevator occupants who are in an emergency situation quickly and surely. Has a useful effect.

In addition, the present invention has the advantage that the manager of the monitoring center can accurately know the contents of the emergency situation or the extent of the occupant through the voice call with the lift occupant can take appropriate measures necessary.

Although the present invention has been described with reference to the accompanying drawings, it will be apparent to those skilled in the art that many various obvious modifications are possible without departing from the scope of the invention from this description. Therefore, the scope of the invention should be construed by the claims described to include many such variations.
